Eight reasons why Ubuntu is the Linux poster child

Filed under
  1. Its large user base. Because Ubuntu is so popular, it becomes even more popular. This viral marketing was the same thing that made YouTube successful.

  2. Hardware support. One of the most common complaints among new Linux users is that their new hardware is not supported by any Linux distribution. Well, with Ubuntu, hardware support is added within days of the hardware coming out.

The KDE 3.5 Control Center - Part 2 - Desktop

Filed under

The Desktop section of the Control Center focuses on the functionality and layout of the desktop(s), the taskbar, and the windows themselves, how they function, behave and what features are turned on or off. This section mostly covers functionality and focuses very little on the actual "eyecandy" experience of the system.

The true nature of open source

Filed under

In the beginning…open source was pure and unadulterated. Over time, the idea of community-build software that is free and unfettered by sticky licensing terms and fees caught on with IT buyers, and the disruption of the old order began.

Debian Etch: first impressions

Filed under

Debian deserves some extra attention. The latest release is being distributed and I have no doubt that it will be installed on quite a few machines over the coming days and weeks.

Brasero does the CD burning job in GNOME

Filed under

My system76 desktop machine came with a CD-RW/DVD-RW drive that I’ve finally got around to trying out. I wasn’t too concerned about how it would work with GNU/Linux, since I suspected CD and DVD burning should be relatively well-supported by now. Of course, you never know until you try.

Linux 4.8.4

I'm announcing the release of the 4.8.4 kernel. And yeah, sorry about the quicker releases, I'll be away tomorrow and as they seem to have passed all of the normal testing, I figured it would be better to get them out earlier instead of later. And I like releasing stuff on this date every year... All users of the 4.8 kernel series must upgrade. The updated 4.8.y git tree can be found at: git:// linux-4.8.y and can be browsed at the normal git web browser: Read more Also: Linux 4.7.10 Linux 4.4.27

Security News

  • Free tool protects PCs from master boot record attacks [Ed: UEFI has repeatedly been found to be both a detriment to security and enabler of Microsoft lock-in]
    Cisco's Talos team has developed an open-source tool that can protect the master boot record of Windows computers from modification by ransomware and other malicious attacks. The tool, called MBRFilter, functions as a signed system driver and puts the disk's sector 0 into a read-only state. It is available for both 32-bit and 64-bit Windows versions and its source code has been published on GitHub. The master boot record (MBR) consists of executable code that's stored in the first sector (sector 0) of a hard disk drive and launches the operating system's boot loader. The MBR also contains information about the disk's partitions and their file systems. Since the MBR code is executed before the OS itself, it can be abused by malware programs to increase their persistence and gain a head start before antivirus programs. Malware programs that infect the MBR to hide from antivirus programs have historically been known as bootkits -- boot-level rootkits. Microsoft attempted to solve the bootkit problem by implementing cryptographic verification of the bootloader in Windows 8 and later. This feature is known as Secure Boot and is based on the Unified Extensible Firmware Interface (UEFI) -- the modern BIOS.
  • DDOS Attack On Internet Infrastructure
    I hope somebody's paying attention. There's been another big DDOS attack, this time against the infrastructure of the Internet. It began at 7:10 a.m. EDT today against Dyn, a major DNS host, and was brought under control at 9:36 a.m. According to Gizmodo, which was the first to report the story, at least 40 sites were made unreachable to users on the US East Coast. Many of the sites affected are among the most trafficed on the web, and included CNN, Twitter, PayPal, Pinterest and Reddit to name a few. The developer community was also touched, as GitHub was also made unreachable. This event comes on the heels of a record breaking 620 Gbps DDOS attack about a month ago that brought down security expert Brian Krebs' website, KrebsonSecurity. In that attack, Krebs determined the attack had been launched by botnets that primarily utilized compromised IoT devices, and was seen by some as ushering in a new era of Internet security woes.
  • This Is Why Half the Internet Shut Down Today [Update: It’s Getting Worse]
    Twitter, Spotify and Reddit, and a huge swath of other websites were down or screwed up this morning. This was happening as hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s probably safe to assume that the two situations are related.
  • Major DNS provider Dyn hit with DDoS attack
    Attacks against DNS provider Dyn continued into Friday afternoon. Shortly before noon, the company said it began "monitoring and mitigating a DDoS attack" against its Dyn Managed DNS infrastructure. The attack may also have impacted Managed DNS advanced service "with possible delays in monitoring."
  • What We Know About Friday’s Massive East Coast Internet Outage
    Friday morning is prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard. This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.
  • Either IoT will be secure or the internet will be crippled forever
    First things first a disclaimer. I neither like nor trust the National Security Agency (NSA). I believe them to be mainly engaged in economic spying for the corporate American empire. Glenn Greenwald has clearly proven that in his book No Place to Hide. At the NSA, profit and power come first and I have no fucking clue as to how high they prioritize national security. Having said that, the NSA should hack the Internet of (insecure) Things (IoT) to death. I know Homeland Security and the FBI are investigating where the DDoS of doomsday proportions is coming from and the commentariat is already screaming RUSSIA! But it is really no secret what is enabling this clusterfuck. It’s the Mirai botnet. If you buy a “smart camera” from the Chinese company Hangzhou XiongMai Technologies and do not change the default password, it will be part of a botnet five minutes after you connect it to the internet. We were promised a future where we would have flying cars but we’re living in a future where camera’s, light-bulbs, doorbells and fridges can get you in serious trouble because your home appliances are breaking the law.
  • IoT at the Network Edge
    Fog computing, also known as fog networking, is a decentralized computing infrastructure. Computing resources and application services are distributed in logical, efficient places at any points along the connection from the data source (endpoint) to the cloud. The concept is to process data locally and then use the network for communicating with other resources for further processing and analysis. Data could be sent to a data center or a cloud service. A worthwhile reference published by Cisco is the white paper, "Fog Computing and the Internet of Things: Extend the Cloud to Where the Things Are."
  • Canonical now offers live kernel patching for Ubuntu 16.04 LTS users

  • ​The Dirty Cow Linux bug: A silly name for a serious problem
    Dirty Cow is a silly name, but it's a serious Linux kernel problem. According to the Red Hat bug report, "a race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system."
